Official Rulings for Mishra's Factory

10/4/2004 : Any counters on the Assembly-Worker remain even if the counters stop being meaningful when it de-animates.
10/4/2004 : If an Assembly-Worker is changed to another land type, it will stay a 2/2 artifact creature and keep the creature type "Assembly-Worker" (until end of turn), but it will change its land type as directed.

8/1/2005 : If another player takes control of the Factory while it is animated, that player keeps control until the control effect ends. They do not lose control just because the card stops being an Assembly-Worker. Note that Auras which steal cards will go to the graveyard if the permanent they enchant is no longer valid.
8/1/2008 : A noncreature permanent that turns into a creature can attack, and its abilities can be activated, only if its controller has continuously controlled that permanent since the beginning of his or her most recent turn. It doesn't matter how long the permanent has been a creature.
10/1/2009 : Activating the ability that turns it into a creature while it's already a creature will override any effects that set its power and/or toughness to a specific number. However, any effect that raises or lowers power and/or toughness (such as the effect created by Giant Growth, Glorious Anthem, or a +1/+1 counter) will continue to apply.
